Application April 7, 1934, Serial No. 719,457 7 6 Claims. (01. 257151) This invention relates to an improvement in radiators for heating purposes and has for its object to provide a device which will, by reason of its construction and design, be particularly effective in performing the functions for which it is intended.

My improved radiator is so constructed that it may be used as a radiator of the so-called built-in type, if desired, or it may be used in .1 the ordinary manner. By a built-in type, I

refer to the type of radiator which is located in a depression or recess formed in the wall.

The primary object of the invention is to provide a radiator of such design that it will present l the aspect of a covered radiator, at the same time greatly increasing its heating elficiency. At the present time, there is a tendency to use radiator covers for the purpose of concealing the generallyconceded ugly radiator in wide use. Many of 29 these covers, which are often merely sheet metal casings, are of such poor design and fit that they greatly impede the normal heating efliciency of the radiator. On the other hand, the covers enhance the appearance of the radiator and prevent the gathering of visible dust and dirt between the radiator sections, so that users are often willing to risk a decrease in heatingeificiency to attain the neatness of appearance which the covered radiator provides.

1' My improved radiator provides the effect of a so-called covered radiator without decreasing the heating efficiency of the radiator, but on the 'other'hand increases the heating efiiciency.

' A'further object of the invention is to provide aradiator with an integrally formed passage by which a flue effect is attained, the outlet opening of the flue or warm air conduit being located at the upper end of the radiator'from which the heated air emanates into the room. This flue or passage is, according to the invention, formed ,by co-operating abutting flanges integrally produced on the contiguous radiator sections, said flanges being situated between the outer longitudinal fluid passages or tubes of the radiator sections. By the use of spaced lugs formed also on the radiator sections, a grille-like structure is provided as a physical part of the radiator proper, this grille being suitably positioned to enable a localized emanation of the heated air to be directed into the room.

In the accompanying drawing forming a part hereof, Fig. 1 is a front elevation of a radiator constructed in accordance with the invention; Fig. 2 is a side elevation of the same; Fig. 3 is a sectional view onthe line .3-3 of Fig. 1, looking in the direction of the arrows; Fig. 4

is a sectional view on the line 44 of Fig. 3, looking in the direction of the arrows; Fig. 5 is a front view of a modified structure; Fig. 6 is a sectional view taken on the sameline as Fig. 4,

of a modified structure; and Fig. 7 is a similar view of another modification.

In the structure shown in Figs. 1 to 4 inclusive, the radiator is shown as composed of a plurality of joined cast metal sections, the intermediate sections being those indicated at 10, and the two end sections at 11. The end sections are provided with downwardly extending legs which rest upon the floor and support the radiator. Each radiator section is composed of a plurality of vertically disposed tubes 13 and 14, and transversely connecting passages 25, the outer tubes being those indicated at 14. Near their upper and lower ends the sections are provided with the bosses 26 which are united in the conventional way to form the water or steam passages through the sections.

The outer tubes 14 of the sections are provided with laterally projecting flanges 15 which abut when the sections are placed together and cooperate to provide a desired flue or air passage between the radiator sections as will be hereafter pointed out. As will be seen from Fig. 4, the flanges 15 located at the front of the radiator extend from a point near the bottom of the radiator to the point 17, located at a short distance below the top. At the back of the radiator, the flanges 15. extend upwardly for the full height of the radiator andthen the flange extends at'right angles or horizontally across the top of the radiator as indicated at 18 in Figs. 1 and 4. The flange portion 18 terminates at 19 at the upper front of the radiator.

Between the points designated at 17 and 19 are spaced abutting lugs 20 formed on and projecting laterally from the radiator sections, these spaced abuttinglugs co-operating as shown in Fig. 1 to iorma grille through which heated air may pass and flow out into the room, as shown 1 0 by the arrows in Fig. 4. i J

The tubes 13 and 14 in the end sections are connected by the integral webs 21, which close the spaces between the tubes. The structure of the radiator is such that a flue arrangement or air conduit is formed by the flanges 15 at the front and back of the radiator, and at the top by the abutting flanges 18. The spaces between the radiator sections are open at the bottom, as is clearly shown in Fig. 4, so that cold air entering between the radiator sections will pass upward through those spaces to enter the flue where it is confined by the flanges 15, 18 and 21 so that it becomes heated and passes out through the grille formed by the spaced co-operating lugs 20.

In Fig. 5 the lugs 20 are omitted and slot-like openings 22 are instead provided between the radiator sections at the front thereof and near the top, these slot-like openings co-operating to form a grille.

In Fig. 6 the lugs 20 are provided at the back of the radiator sections as well as at the front,

near the top, so that two grilles are provided on.

opposite sides of the radiator and the heated air rising between the radiator sections will pass out and into the room on both sides of the radiator. This type of radiator is particularly advantageous when the radiator is located externally of and not in a wall recess.

In Fig. 7 a radiator is shown wherein the longitudinal flanges l5 terminate at the upper end of the radiator sections and lugs 23 are provided at the top of the sections so that a top grille is formed through which the heated air passes. It will be seen that the flangesl5 and lugs 29 or 23 are formed between the tubes of the radiator sections and co-operate to provide flat surfaces between the tubes. The general effect-and appearance of an ordinary radiator is provided with the advantages of a covered radiator.

The extra expense of casting on the flanges and lugs, as well as the material required is inconsequential and the increase in heating efficiency is considerable. By the formation of the spaced co-operating lugs on the radiator sections, an integral grille is provided, thus obviating the use of a separate attached grille and fastening means therefor.

What I claim is:

1. In a radiator assembly, a plurality of sections connected togetheneach of said sections being formed at their front and rear with laterally extending flanges, said flanges being spaced inwardly from the front and rear edges of the sections and located in abutting relationship to form an air passage between them, and spaced lugs formed on the sections inwardly from the outer edges thereof and abutting against one another to form a grille through which heated air passing through the air passage between the flanges emanates.

2. In a radiator assembly, a plurality of connected radiator sections, said sections being each formed with laterallyextending spaced lugs located inwardly from the outer edges of the sections, the lugs on one section being located in abutment with those on the next so that the cooperating abutting lugs form a grille between and inwardly spaced from the outer edges of the sections.

3. In a radiator assembly, a plurality of connected radiator sections, said sections being each formed with a plurality of spaced lugs spaced inwardly from the outer edges of 'the sections, the lugs on one section being. located in abutment with those on the next so that the co-operating abutting lugs form a grille between the sections and spaced inwardly from the outer edges of the sections, and abutting flanges formed on the sections below the grille to form an air passage below the grille.

4. A radiator assembly composed of a plurality of hollow connected end and intermediate radiator sections, said sections being provided near their longitudinal edges with flat flanges so that when said sections are placed together they will present continuous substantially plane surfaces in the spaces between their outer longitudinal faces, said surfaces extending between the sections across the front, back and top of the radiator, the flanges in said sections being interrupted at the bottom and at the upper end of the front of the radiator whereby an air channel is provided between the sections, said channel beginning at the exposed bottoms of the sections and terminating at the upper front thereof, the sections being providedat the upper front thereof with spaced lugs co-operating to'form an integral grille on the radiator at the upper end of the channel.

5. A radiator assembly composed of a plurality of hollow conn cted end and intermediate radiator sections, said sections being provided in wardly from their longitudinal edges with flat flanges so that when said sections are placed together they will present continuous substantially plane surfaces in the spaces between their outer longitudinal faces, said surfaces extending between the sections across the front, back and top of the radiator, the end sections of the radiator being closed, the flanges in the various radiator sections being interrupted at the bottom and at the upper end of the sections at the front and rear thereof whereby an air channel is provided between the sections, said channel beginning at the exposed bottoms of the sections and terminating at the upper front and back thereof, the sections being provided at the upper front and back thereof with spaced lugs co-operating to form integral grilles on the radiator at the upper front and back-thereof at the upper end of the air channel.
